High-Grade Gold Mineralization At Sona Hill 

DENVER, CO - Sandspring Resources Ltd. reported the completion of the 2016 exploration program at its measured and indicated 6.9 million ounce resource Toroparu Gold Deposit in Guyana, South America. The 2016 Program for drilling at the Sona Hill Satellite Deposit consisted of 8,084 meters (m) of infill and step out drilling. The results of the first 20 infill holes (2,776m) were reported. Highlights from results of the remaining 4,568m infill and 740m step-out drilling program at Sona Hill include 7.89 g/t Au over 13.5m in Sona Hill Drill Hole ("SOD")081 (infill), 39.56 g/t Au over 10.5m in SOD090 (infill), 3.58 g/t Au over 14.6m in SOD097 (infill), 1.94 g/t Au over 28.5m in SOD100 (infill), 2.49 g/t Au over 15.7m in SOD-107 (step-out), and 4.91 g/t Au over 3.0m in SOD109 (step-out).

The 2016 Program for Wynamu Hill consisted of 1,127m of drilling. Highlights from the discovery of gold mineralization in saprolite and fresh rock include 1.18 g/t Au over 19.5m in Wynamu Drill Hole (WYD) 003 and 7.51 g/t Au over 21.5m in WYD013.

The 2016 Program also included completion of geochemical and geophysical surveys west of Sona Hill, and infill geochemical sampling at the Otomung concession, which is located 25 km to the northwest of Toroparu.

Rich Munson, CEO said, "We are very pleased to have completed the 2016 Program on schedule and within budget and to be able to report both continuing positive results at Sona Hill and the presence of an additional potential satellite deposit at Wynamu Hill. We are further encouraged that these near-surface systems contain areas of higher grade mineralization and remain open at depth and on strike, providing the potential for gold-only satellite deposits in proximity to existing reserves that could have a meaningful impact on the development of Toroparu. Exploration success to the southeast of Toroparu at Sona Hill, to the northwest at Wynamu Hill, and encouraging results from geochemical surveys at Otomung further supports our geologic model for the area, and we expect the detailed evaluation of the results will support further exploration efforts in these areas as well as the other high priority gold features within the 20 km by 7 km regional hydrothermal alteration halo surrounding Toroparu."
